There's a lot we don't understand.
My son went from mild/moderate to bedridden/barely conscious after one sports game (although he was only that severely ill for a month). My daughter kept pushing herself physically in substantial ways, and crashing, and yet recovered after a couple of years.
I guess a precautionary approach would suggest that avoiding PEM is probably a good thing to try to do, given how many people say that activity caused a deterioration that they didn't recover from. But, the people who did the body-building sessions and crashed and went on to recover probably aren't posting on that reddit thread. I think we need to keep in mind the range of illness trajectories, and avoid sounding certain.
